Abstract

Claims (29)

1 . A device comprising:

at least two electrically distinct layers being mechanically stacked, wherein the at least two electrically distinct layers are electrically independent and operate independently within the device, and the at least two electrically distinct layers comprising:

a bottom layer comprising one or more silicon cells, and

an upper layer comprising one or more transmissive solar cells that convert a first portion of a light energy into and outputs a first electricity and transmits unconverted portions of the light energy towards the bottom layer, and

wherein the bottom layer separately, from the first electricity, converts at least part of the unconverted portions of the light energy into and outputs a second electricity.

2 . The device of claim 1 , wherein the device generates a total power conversion efficiency from the first electricity and the second electricity.

3 . The device of claim 1 , wherein the device comprises a reflective layer adjacent to the bottom layer.

4 . The device of claim 1 , wherein the mechanical stacking of the at least two electrically distinct layers vertically aligns the one or more silicon cells with the one or more transmissive solar cells.

5 . The device of claim 1 , wherein the device comprises two or more electrically distinct strings, and

wherein each of the at least two electrically distinct layers is correspondingly connected to an electrically distinct string of the two or more electrically distinct strings.

6 . The device of claim 1 , wherein the mechanical stacking to vertically align the one or more silicon cells of the bottom layer with the one or more transmissive solar cells of the upper layer increases a power conversion efficiency of the device compared to a power conversion efficiency of the bottom layer alone in the device.

7 . The device of claim 1 , further comprising:

a support structure securing the mechanical stacking of the at least two mechanically stacked layers.

8 . The device of claim 1 , wherein the one or more silicon cells of the bottom layer comprises a transmissive solar cell.

9 . A system comprising:

at least two electrically distinct layers being mechanically stacked, wherein the at least two electrically distinct layers are electrically independent and operate independently within the system, and the at least two electrically distinct layers comprising:

a bottom layer comprising one or more silicon cells, and

an upper layer comprising one or more transmissive solar cells that convert a first portion of a light energy into and outputs a first electricity and transmits unconverted portions of the light energy towards the bottom layer, and

wherein the bottom layer separately, from the first electricity, converts at least part of the unconverted portions of the light energy into and outputs a second electricity.

10 . The system of claim 9 , wherein the device generates a combined power conversion efficiency from the first electricity and the second electricity.

11 . The system of claim 9 , wherein the device comprises a reflective layer adjacent to the bottom layer.

12 . The system of claim 9 , wherein the mechanical stacking of the at least two electrically distinct layers vertically aligns the one or more silicon cells with the one or more transmissive solar cells.

13 . The system of claim 9 , wherein the system comprises two or more electrically distinct strings, and

wherein each of the at least two electrically distinct layers is correspondingly connected to an electrically distinct string of the two or more electrically distinct strings.

14 . The system of claim 9 , wherein the mechanical stacking to vertically align the one or more silicon cells of the bottom layer with the one or more transmissive solar cells of the upper layer increases a power conversion efficiency of the device compared to a power conversion efficiency of the bottom layer alone in the device.

15 . The system of claim 9 , further comprising:

a support structure securing the mechanical stacking of the at least two mechanically stacked layers.

16 . The system of claim 9 , wherein the one or more silicon cells of the bottom layer comprises a transmissive solar cell.

17 . The device of claim 1 , wherein one or more of the at least two electrically distinct layers being mechanically stacked are configured for removal from the device to enable installation of one or more electrically distinct substitute layers in the device that corresponding and separately generate the first or second electricity.
